Description

Climbing ladder device for well chamber

Technical Field

The utility model relates to a well room cat ladder device.

Background

The well chamber is a special underground structure which is used for connecting upstream and downstream pipelines, connecting branch pipes or is arranged at the position of pipeline accessories such as valves, compensators and the like in real life and is used for operation and maintenance of maintenance personnel. Generally, the building is built by brick laying, concrete or reinforced concrete cast-in-place or prefabricated structures.

The system is convenient to install and is arranged based on the maintenance of power supply, water drainage, pollution discharge, communication, cable television, gas pipes, street lamp lines and the like of the urban underground infrastructure at the present stage. It is usually installed at the intersection of pipelines, turning, where the pipe diameter or slope changes, and at certain intervals on straight pipeline sections, and is convenient for regular inspection of the attached structures. The well chamber is built by laying bricks or stones the initial stage and all can be in the simple and easy cat ladder that gets into the well chamber and overhaul of being convenient for of interior installation, because general inspection well head is flat mutually with ground or the well head is less than ground height on every side, when inspection maintenance personnel passed through the cat ladder about the inspection shaft, all need lie prone the health on ground or both hands support ground just can pass in and out the well chamber earlier, will cause like this that personnel fall into the well chamber risk, also can lead to the clothes to become dirty scheduling problem to take place because surrounding environment factor simultaneously. From safe and convenient angle, a specially designed cat ladder that is convenient for maintenance and inspection personnel to pass in and out well room. The ladder stand is simple in structure, safe, reliable and convenient to use, guarantees the safety of maintenance personnel, is low in manufacturing and installing cost, simple in structure, and can be widely applied to the fields of electric power, heat supply, water supply and drainage, communication and the like.

Disclosure of Invention

The utility model aims at providing a safe, simple, convenient well room cat ladder device. The technical scheme of the utility model is that: a climbing ladder device for a well room comprises a well room (1), an embedded steel bar handrail (2), a first welded steel pipe (3), a second welded steel pipe (4), a third welded steel pipe (5), a fourth welded steel pipe (6), an anti-collision ball (7) and a climbing ladder hook (8), wherein the first welded steel pipe (3) is welded at two sides of the embedded steel bar handrail (2), the second welded steel pipe (4), the third welded steel pipe (5) and the fourth welded steel pipe (6) are assembled and welded into a whole, the second welded steel pipe (4) and the transverse fourth welded steel pipe (6) are welded and fixed into a Chinese character 'ri' shape with two ends extending out, the fourth welded steel pipe (6) and the third welded steel pipe (5) are longitudinally welded and fixed into a Chinese character 'T', and the anti-collision ball (7) is welded at the top of the second welded steel pipe (4), the third welded steel pipe (5) in the movable ladder (9) is inserted into the inner wall of the top of the first welded steel pipe (3) to form a whole.

The well chamber (1) is constructed by red bricks.

The structural form of the well chamber (1) is concrete pouring.

The movable ladder (9) is formed in a welding mode.

The utility model discloses a theory of operation:

the utility model discloses will before getting into the inspection shaft room, the back is opened to the well room apron, carry out the forced draft to the well room and handle, guarantee that the harmful gas in the airtight space is whole to get rid of, and carry out gaseous detection back to the well room inner space with the gas detection appearance, portable cat ladder (9) of hanging on well room lateral wall cat ladder couple (8) are taken up, insert first welding steel pipe (3) top inner wall with third welding steel pipe (5) of portable cat ladder (9) lower part this moment, guarantee not hard up, the condition such as crooked, inspection personnel both hands hold portable cat ladder (9) just can get into the well room and carry out the operation this moment, upwards scramble along embedded bar handrail (2) after the operation is accomplished, operation personnel both hands hold portable cat ladder (9) side body and can conveniently step on to the well room outside when climbing the top. The movable crawling ladder (9) is required to be exposed out of the well chamber by 500mm, a person can conveniently enter and exit the well chamber during the purpose, and the movable crawling ladder (9) can be coated with black and yellow paint or pasted with a warning sticker so as to prompt passing pedestrians and vehicles to operate at the place and enhance the warning effect.

The utility model discloses technological effect:

the utility model relates to a know that there is the risk problem in well room business turn over operation. When the inspection personnel pass through the ladder and go in and out the inspection shaft from top to bottom, all need lie prone the health on ground or both hands support ground just can go in and out the well room earlier, will cause personnel to fall into the well room risk like this, also can lead to the clothes to become dirty scheduling problem to take place owing to surrounding environment factor simultaneously. From safe and convenient angle, a specially designed cat ladder that is convenient for maintenance and inspection personnel to pass in and out well room. The ladder stand is simple in structure, safe, reliable and convenient to use, guarantees the safety of maintenance personnel, is low in manufacturing and installing cost, simple in structure, and can be widely applied to the fields of electric power, heat supply, water supply and drainage, communication and the like.
